Terminal block range has advanced marking system

An ABB Automation Tech (LV Products) product story

Edited by the Engineeringtalk editorial team May 7, 2009

ABB has announced the launch of the SNK terminal block range, which gives users a selection of electrical connection devices offering a range of options in a reduced number of variants.

With 220 terminals and accessories in the range, the SNK series has been specifically designed to simplify the process of terminal block selection and stockholding while ensuring a suitable option for every need.

The development of a single version that meets standards including Atex, UL, UL94 V0, Gost, CSA, and RoHS, makes it easier for users to select the correct variant for their requirements.

It eliminates the need for separate blocks for each standard and makes it easier for users to ensure they have the correct device installed.

The availability of UL94 V0 as standard also makes the SNK ideal for use in railway applications.

The SNK series is available in sizes from 4mm2 to 95mm2 as feed-through terminals, accepting cables down to 0.2mm.

Double-deck and disconnect versions are also available in 4mm2 and an optional 6mm2 size, if required.

Completing the range are fuse terminals, which accept 5 x 20mm and 5 x 25mm fuses.

A further reduction in the number of variants has been achieved by the creation of three endplate options, with a single option covering sizes up to 16mm.

A key feature of the SNK terminal range is its reduced size, with terminal width reduced by up to 3mm.

In a typical installation, this could add up to a total space saving of up to 25 per cent, enabling users to reduce the overall size of their enclosures.

This reduction in size has been achieved without affecting the product's conformity to the IEC60947-7-1 standard for wiring connection.

To help speed up wiring times, SNK terminals feature a computer-designed cable guide to ensure cables are properly inserted, with up to two cables able to be fitted to each terminal.

As a further aid to fast installation, up to 10 blocks can be locked into place at a time.

To ensure a safe connection, an anti-release screw design prevents wires from becoming loose.

Where a push-in jumper bar is used, the SNK's 'positive-click' feature ensures a sound connection, audibly clicking into place when fitted correctly.

Another feature of the SNK range is its advanced marking system.

Developed in consultation with terminal users, this system offers users a wide choice of marking options, ranging from pre-printed markers through to blank markers that can be either printed on a normal desktop printer or handwritten.

Wire markers are also available where required.

In contrast with conventional terminal markers, which are supplied as strips, the SNK's markers are separated when installed, enabling users to remove and replace a single block if required.

To improve marker visibility, the SNK series features an asymmetrical design, enabling markers to be clearly read in any orientation.

A patented flat marker space has also increased the available marker area by 20 per cent, further aiding easy identification of terminal functions.

Carrying both ABB and Entrelec branding, the SNK range complements ABB's existing 5000 terminal block series for industrial applications.

The SNK range is now available from ABB's strategic industrial partner network.
